An inductoris a passive two-terminal electrical component used to store energy in a magnetic field. Any conductor has inductance although the conductor is typically wound in loops to reinforce the magnetic field.Inductors are one of the basic components used in electronics where current and voltage change with time, due to the ability of inductors to delay and reshape alternating currents.

Inductors called chokes are used as parts of filters in power supplies or can be used to block AC signals from passing through a circuit. LD2-220-R Coiltronics/Div of Cooper/Bussmann INDUCTOR PWR METL DRUM CORE 22UH
Inductors are used extensively in analog circuits and signal processing. Inductors in conjunction with capacitors and other components form tuned circuits which can emphasize or filter out specific signal frequencies.LD2-220-R Coiltronics/Div of Cooper/Bussmann INDUCTOR PWR METL DRUM CORE 22UH
This energy transfer ratio determines the input-voltage to output-voltage ratio. This XL is used in complement with an active semiconductor device to maintain very accurate voltage control.LD2-220-R Coiltronics/Div of Cooper/Bussmann INDUCTOR PWR METL DRUM CORE 22UH
Inductors are also employed in electrical transmission systems, where they are used to depress voltages from lightning strikes and to limit switching currents and fault current. In this field, they are more commonly referred to as reactors.LD2-220-R Coiltronics/Div of Cooper/Bussmann INDUCTOR PWR METL DRUM CORE 22UH
